WILLIAM S. HADAWAY, JR., OF EAST ORANGE, NEW JERSEY, ASSIGNOR TOWESTING- HOUSE ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION OFPENN- SYLVAN IA.

MATRIX-DRYING PRESS.

To all whom it may concern:

Be it known that I, \VILLIAM S. HADA- way, J r., a citizen of the UnitedStates, and a resident of East Orange, in the county of Essex and Stateof New Jersey, have invented a new and useful Improvement 1nMatrix-Drying Presses, of which the following is a specification.

My invention relates to matrix drying presses embossing presses andslmllar devices, and it has for its object to provlde a device of thischaracter which shall be simple and durable in construction andelectrically operated, and which may be provided with one or moreelectrically heated working surfaces.

Patent No. 890,858, granted June 16, 1908, to the Hadaway ElectricHeating & Englneering Co., upon an application filed by me, illustratesand describes an electric heater which is well adapted for use inconnection with stamping and embossing press machinery, and it is oneofthe purposes of my present invention to embody a like or similar heaterin a book-binder press or similar device which, for purposes ofsimplicity, is also electrically operated. I also contemplate theemployment of means for electrically operating presses of the characterindicated above whether they are or are not electrically heated.

Figure l of the accompanying drawings is a plan view and Fig. 2 is anelevation of a press constructed in accordance with my invention, F 1g.3 1s a diagrammatic vlew of the circuit connections for the device shownin Figs. 1 and 2, and F 1g. 1 shows the electric heater whlch forms oneof the worklng 'surfaces of the device.

Referring to Figs. 1 and 2 of the drawings, the device here showncomprises a stationary frame or base 1 having vertical guide ways 2projecting upwardly therefrom, and a cross beam 3; a stationary workingsurface plate 4. which is electrically heated, and a movable workingsurface plate 5 which is adjustably connected to the cross beam 3 and iselectrically operated. A supporting carriage 6 is adjustably secured tothe cross beam 3 by means of suspension bolts 7 and is guided in itsmovement toward and away from the cross beam by projections 8 whichregister with the guide ways 2. The heads of the suspension bolts 7 areprovided with beveled gears 9 and a Specification of Letters Patent.

Application filed May 1, 1909.

Patented Jan. 30, 1912. Serial No. 493,407.

horizontal shaft 10 is so supported in projections 11 on the cross beam3 that beveled pinions 12, with which it is provided, are adapted tomesh with the beveled gears 9. In this way, the concurrent rotation ofthe gears 9 may be effected by means of a hand wheel 13, which issecured to the outer end of the shaft 10, and an adjustment of thecarriage 6 may be obtained This carriage 6 is provided with downwardlyextending projections 14 which correspond, in position, to a pair ofupwardly extending projections 15 on the working surface plate 5. Theplate 5 is suspended from the plate 6 by two pairs of links 16 and 17which are pivoted to the projections 14 and 15. An operatingelectro-magnet 18 is located bet-ween the plates 5 and 6, with its axishorizontal, and is provided with a pair of similar armatures 19 and 20,both of which are movable and the outer extremities of which areseparately pivoted to the points of connection between the links 16 and17. The arrangement of parts is such that when the plate 5 is raised outof engagement with the work, by means of the hand wheel 13, thearmatures 19 and 20 come together at the center of the coil 18, but,when some article 21 is laid in the matriX space on the plate 1 and theplate 5 is lowered into engagement with it, the weight of the plate 5will first be borne by the article 21 and then, as the hand wheel isfurther adjusted in the same direction, the armatures 19 and 20 will beslightly separated, as shown in Fig. 2 of the drawings.

The operation of the device will be more readily understood by referenceto Figs. 3 and 4. If it is assumed that the work to be pressed is inposition and that the movable plate 5 has been brought intoengagementwith it, as indicated above, electrical energy may be suppliedfrom any suitable source, such as a generator 22, through conductor 23to terminal 24 of a control switch 25. From this point, the circuit maybe completed either through the electric heating device 4, which formsthe stationary working surface plate of the press, alone or through theheater and the operating coil 18, according as the switch 25 is throwninto engagement with contact member 26 or with both contact members 26and 27. It will probably be unnecessary to separate the contact members26 and 27 for, if it is always desired to energize the magnet windingand the heater at the same time, these members may be electricallyconnected, either in series or in multiple circuit, a single switchbeing provided for interrupting the circuit, in either case.

Vi hile only the stationary working surface of the press shown in thedrawings is adapted to be electrically heated, it may be found desirableto provide a heater for the movable plate or for both plates. The scopeof my invention is not, however, restricted to a press havingelectrically heated parts and this point will be determined by theservice for which the device is intended.

It may be found desirable to insert an eX- ternal variable resistanceinseries with the electric heating device for or to provide a controllerfor changing the internal connections of the heater in order to obtainan adj ustment of the heat generated.

It will, of course, be readily understood that the operating magnet maysimilarly be controlled if an adjustment of the pressure exerted by themagnet is required. A certain degree of variation may be obtained in thepressure exerted by the magnet by suitably adjusting the hand Wheel 13,since the air-gap existing between the movable armature members may, inthis way, be varied.

It is evident that various modifications may be effected in the deviceillustrated without departing from the spirit of my invention, and Idesire that only such limitations shall be imposed as are indicated inthe appended claims.

I claim as my invention:

1. A press comprising an electrically heated working-surface plate, anelectrically operated workingsurface plate and a single means forgoverning the supply of energy to both members.

2. A press comprising an electrically heated stationary working-surfaceplate, a

mechanically adjustable movable member having a cooperatingworking-surface plate suspended therefrom, electro responsive means foractuating said plate and a single switching device for governing thesupply of energy to both members.

3. In a press, the combination with a stationary frame, vertical guideproject-ions extending upwardly therefrom, and a cross beam mounted onthe projections, of an electrically heated working-surface plate securedto the frame, a suspension plate adjustably depended from the crossbeam, a cooperating surface plate connected to the suspension plate bylinks, and an operating electro-magnet for so separating the movablesurface plate and the suspension plate as to move the surface plate intoengagement with the electrically heated surface plate.

i. A press comprising a movable working-surface plate, an adjustablecarriage, toggle links between the carriage and the plate, andelectro-responsive means for actuating the toggle links to forciblyseparate the plate from the carriage.

5. A press comprising an adjustable carriage, a working-surface plate,an electro magnet between said members having a pair of similararmatures or cores, and toggle links connecting the plate to thecarriage, said armatures or cores being operatively connected to thelinks.

In testimony whereof, I have hereunto subscribed my name this 20th dayof April,

Copies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,
